Engines, of which he following is a specication.

My present invention relates to improvements in the art embracinginternal combustion engines, and more particularly to a specific typeofrotary motor which can be operated at anabnormally. high speed andwhich will develop a maximum degree of power and eflicienc The object ofmy present invention is to provide such a motor, extremely simple inconstruction and of few parts, and one that will run smoothly, and inwhich friction is reduced to a minimum.

Another object resides in the provision of a rotor journaled within awater-jacket, said rotor being of smaller diameter than the jacket anddisposed therein similar to a rotatable spool. A disk or fin integralwith the water-jacket extends intermediate the two flanges of the rotor,and serves to divide the same into cylinders.

Having these and other objects of general utility and design in view, I-have, illustrated a preferred embodiment of my invention in theaccompanying drawings, in which Figure 1 is a 11 of Fig. 4.

Fig. 2 is a view at right angles to 1.

Fig. 3 is a fragmentary section showing the arrangement of the intakeports.

Fig. 4.- is a transverse section on line H of Fig. 1.

Fig. 5 is a view of the rotor from the casing of the motor.

Fig. 6 is a schematic view showing the relative arrangement of thevalves.

vFig. 7 is a similar view the valves being in their extreme outerposition from that as shown in Fig. 6.

Fig. 8 is an enlarged fragmentary detail elevation of one of theabutments, and

Fig. 9 is a transverse section therethrough disassembled I on line 9-9.

Similar reference characters referrespectively to similar partsthroughout the several views.

y invention consists in providing a substantially cylindricalwater-jacket 10, which cross sectional view on line .tor. The exhaustport is mounted upon the usual base 11, with a vertical centrallydisposed web or fin 12, integral therewith and substantially dividmg theinterior of the jacket 10, or chamer, into two similar compartments, inthis case, to-form the opposed cylinders of my engine.

The rotor of my stantially spool-shaped member, 13, and 1 a swingingpiston '19, surface of which is also provided with suitable packing 20.Into the respective cylinders leads a fuel intake, 21, and leadingtherefrom an exhaust port,

stantlally adjacent the abutments, 16, I lead a spark plug, 23 withsuitable electrical connections, not shown, but so timed as to sparkwhen the parts are in a position as shown in Fig. 6.

From the foregoing it will be apparent the surfaces of the pistonsforming abutments, and ignition of the gas taking place at this point,the pressure will be applied against the pistons, thus revolving therois positioned at substantially 45 degrees from the intake, so that theburnt gases are driven forward of the rotating swinging pistons, 19, andforced out from the compartment. 0

erein I have shown and described my invention for use in connection withan explosive gas, I wish it understood that the same principle may beadvantageously em bodied in a motor employing steam as a motive power.

What I claim is 1. A rotary engine comprising a cylin-- drical comartment havin intake and ex- 16, is radially forming the cylinde: heads,opposed compartments, one on the outer face of each flange, a swingingpiston pivoted in each compartment, and a partition integral with saidcylindrical compartment and having an abutment thereon engaged by saidswinging pistons.

'2. A rotary engine comprising a cylindrical compartment, a centrallydisposed web having a radial abutment thereon, said web dividing" thecompartment into two similar apartments, each apartment being providedwith an inlet and exhaust port,

a spool-shaped rotor journaled in the web and a swinging piston pivotedon each flange 01": said rotor, the flanges of said rotor forming theheads of the respective cylinders.

in testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two subscribing witnesses.
